Emma is working to finalize the physical headband. The base of the headband has been constructed, and she has verified that it fits our device specifications in terms of the amount of the head that it covers. She is working to secure the use of a sewing machine in order to construct the pocket that will hold the IMU in the headband, thereby completing the headband portion of the device. Emma also began looking into the final report and particularly the DesignSafe analysis. The DesignSafe program proved to be confusing and potentially difficult to use with our product, but she is currently gathering more information about how we can best use it for our device.
Thom got the calibration loop working this week - a button press activates a loop in the Arduino program. However, it triggers some sort of FIFO (first in first out) overflow that causes NaN (not a number) to be displayed for one of our yaw-pitch-roll values. He is currently working to resolve this issue. Katelyn is working with the Raspberry Pi and got some advice from a friend about how best to avoid timing issues when getting input from the Raspberry Pi from the Arduino Serial monitor. However, she is getting input from the Serial monitor, and just needs to figure out how to fine tune the timing (some of the inputs get cut off partway) and how to get the correct output from the Pi as a result.
